I installed gnome-session gnome-shell-extensions. I did not install budgie, because the test plan at https://wiki.ubuntu.com/DesktopTeam/TestPlans/Mutter says it's not needed for 23.10. Each login, I selected a different session from this list: GNOME, GNOME Classic, Ubuntu, Ubuntu on Xorg. In each session, I did: - play 4k youtube video in full screen in firefox and chrome. For the next steps, I left firefox playing that video while conducting the other checks - verified that firefox was using hardware acceleration (chrome isn't, that's known) - sent a notification via notify-send, observed it was displayed - did a large file copy with the file manager. First, locally, then over the network using SMB. I did not observe any stuttering during these verifications, nor any other ill effect. The hardware this was tested on is a ThinkPad X1 Carbon Gen 10 with an Intel Alderlake_p (Gen12) video system. ** Tags removed: verification-needed-mantic ** Tags added: verification-done-mantic -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2046360 Title: Heavy stuttering in Firefox with mutter 45.1/45.2 Status in mutter package in Ubuntu: New Status in mutter source package in Mantic: Fix Committed Bug description: There is heavy stuttering visible in Firefox with mutter 45.1/45.2.
